Manufactured from solid micrograin carbide and finished with a PVD-applied TiN coating, this insert delivers consistent cutting performance across a broad range of workpiece materials. The 1\/2 inch inscribed circle and 0.187 inch thickness conform to standard 22IR insert geometry. The 29-degree included angle matches Stub Acme thread form requirements. Licensed machinists and CNC lathe operators working in production or job-shop environments are the primary users of this insert.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for internal threading operations on lathes equipped for laydown-style tooling. The Stub Acme thread form is common in lead screw assemblies, linear actuators, and power transmission components across both light industrial and commercial manufacturing applications. The universal material grade designation means this insert can be applied across a wide range of workpiece materials including steel, cast iron, stainless, non-ferrous alloys, and high-temp alloys corresponding to material codes H, K, M, N, P, and S.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for wear resistance and edge stability\u003c\/li\u003e\n  \u003cli\u003ePVD TiN coating reduces friction and extends tool life in continuous threading passes\u003c\/li\u003e\n  \u003cli\u003e29-degree included angle machined to Stub Acme thread form standard\u003c\/li\u003e\n  \u003cli\u003eRight-hand internal threading geometry for standard bore thread cutting\u003c\/li\u003e\n  \u003cli\u003eUniversal workpiece material compatibility covering steel, stainless, cast iron, non-ferrous, and high-temp alloys\u003c\/li\u003e\n  \u003cli\u003eCE certified and manufactured under ISO 13485:2016, ISO 14001:2015, and ISO 45001 quality systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct application insert for 22IR laydown threading toolholders requiring a 1\/2 inch inscribed circle insert suited to Stub Acme internal thread profiles at 4 TPI.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or removing the insert. Use the appropriate torx or hex key specified by the toolholder manufacturer to secure the insert clamp to the recommended seating torque per the holder documentation. Inspect the insert pocket and clamp for debris or damage before installation to ensure proper insert seating.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: 22IR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 22\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Right Hand Internal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: Stub Acme\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThreads Per Inch\u003c\/strong\u003e: 4 TPI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 29 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inches (1\/2 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.187 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: MXC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN (PVD Applied)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Codes\u003c\/strong\u003e: H, K, M, N, P, S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: CE, ISO 13485:2016, ISO 14001:2015, ISO 45001\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: CARMEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 22UIR4STACMEMXC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CARMEX","offers":[{"title":"Default Title","offer_id":52030469701938,"sku":"22UIR4STACMEMXC","price":374.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c964e50ddcbf5099d77500c303afbd17.jpg?v=1790019386","url":"https:\/\/voomisupply.com\/products\/carmex-22uir4stacmemxc-threading-insert-4-tpi-1-2-in-ic","provider":"Voomi Supply","version":"1.0","type":"link"}
